Robinson was a baseball fan, cofounder of the New York Black Yankees ball team which played in the Negro National League between 1936 and 1948. Co-founded by Robinson as the Harlem Black Bombers, the team adopted the name Black Yankees in 1936. It wasn’t until 1948 that Major League Baseball was officially desegregated. The photograph Robinson mentions in this letter measures 3 1/4 x 4 1/2 inches and shows the famed dancer possibly dancing up the steps from the dugout. The dugout may be that of the Black Yankees. He thanks his correspondent for the photo. "I shall keep it for my private album - Well it looks as if we will have the World's Series right here again. Do hope I can be near enough to see one or two games...." He signs, "'Copesetically' Bill Robinson." With printed personalized transmittal envelope.
The third game of the 1942 National Negro Leagues World Series was played in Yankee Stadium between the Kansas City Monarchs and the Homestead Grays.
